FIELD OF APPLICATION OF HEATING ELEMENTSIn comparison with other means of heating, the electrical heating elements have many advantages (lower dimensions, high

efficiency, easy controllability and protection, safe handling, easy maintenance and quick exchange, high reliability and long lifetime) and thus can be considered as a general-purpose heating means for various media and environments, for electricalappliances as well as for parts of machines and devices.

Backer Elektro CZ produces a wide assortment of high quality sheathed tubular heating elements that can be, from the physicalpoint of view, divided into elements intended for heating of gases (air and technical gases), liquids (water, solutions, oils, viscousliquids etc.) and contact heating of solid state materials (e.g. parts of electrical appliances, moulds for plastics, parts of industrialmachines and devices, tramway and railway switches etc.).

New in our assortment: Electrical heating elements featuring a waterproof vulcanized rubber sealing covering the connectionbetween the element and the connecting cables. These elements are intended for devices and areas with extremely highhumidity, with intensive steam generation or in direct contact with water.

Recently, a special attention is dedicated to thick film heating elements, the most advanced and elegant method of heating inmany of the above mentioned applications. Backer Elektro CZ has a wide know how in this field and the company is equippedwith an advanced low series manufacturing technology equipment for production of these elements. The company is ready toenlarge the production capacity substantially in case of higher demand for these progressive heating elements.

Individual applications of electrical heating elements are given below at the respective product groups, including typicalrepresentatives for a given group. This catalogue is not intended (and it would have been also hardly achievable for practicalreasons) to give information on the whole assortment of heating elements within Backer Elektro CZ, as this assortment includesseveral hundreds of types and models. Instead, the company intends to introduce here its capabilities and potentials built onlong term know how and experience, while the specific requirements of a customer will be maximally satisfied after bilateraldiscussions and consultations of both parties.

For better understanding, we also specify basic technical parameters at the end of the catalogue, the combination of whichwill result in optimum characteristics of the heating element that will meet the expectations and requirements of the customerand that will serve reliably and satisfactorily. This is the main effort and aim of all employees of Backer Elektro CZ - your partnerin electrical heating.

THICK FILM HEATING ELEMENTS

These heating elements are intended for contact heating of flat surfaces and for heating of liquids through aflat wall. Compared with an ordinary tubular heating element, a heating element on a sheet metal providessubstantially better heat transfer into a flat wall. These elements can also be of benefit in applications, wherelow thickness of the heating element is important.

Considering the application of thick film elements, a consultation with the Technical Department of BackerElektro CZ is highly recommended for detailed specification of particular requirements. For betterunderstanding of the specific features of thick film heating elements, an Application List with customer’sreferences has been issued; it can be e-mailed on request.

The heating elements meet the requirements of standard EN 60335-1 – Safety of electrical appliances.Please, observe local regulations for installation and connection to the electric network.

Field of application

• various kinds of contact heating• cooking plates and boards• electrical household appliances• water heating in storage and

instantaneous water heaters• water heating in washing machines• water boiling kettles, deep fat

fryers• irons, cookers

43

Thick film heating elements are manufactured in a completely different way than ordinary tubular heating elements. A thick filmheating element consists of a stainless steel or ceramic substrate (plate), on which an insulation layer (meets the requirementsfor dielectrical strength) is printed, then a layer of resistive paste, followed by a contact and connective layer, and finally all theselayers are covered with top enamel layer (providing just protection against mechanical damage, does not meet the requirementsfor dielectrical strength. The individual layers are applied by screen printing and each layer is dried and fired afterwards.Maximum protection from dirt and dust is essential through the whole production process. Production runs in air-conditionedareas meeting the requirements for rooms with high air purity class.

Thus precisely manufactured thick film heating elements feature a quick temperature rise, an extremely low thermal capacity and minimum temperature fluctuations. Their high efficiency of 70 - 95% depends on the mode of operation (direct or indirectheating).

At Backer Elektro CZ, substrates made of stainless steel according to standards AISI 430, DIN 1.4016 are used. Test withstainless steel AISI 304, DIN 1.4301 were carried out as well. The substrate (printing area) must be flat, but can be of variousshapes and can contain openings manufactured in advance (before the printing process).

The elements operate at standard line voltage (up to 400 V). Thick film heating elements feature very high surface power density(up to tens W/cm2). Nevertheless, their operation conditions should be adjusted according to the particular application -adequate heat transfer should be provided so that the surface temperature does not exceed 300 °C.

Thick film heating elements feature a significant PTC effect (its resistance rises with rising temperature, so its power decreasesconsecutively). Thus, resistance at room temperature and nominal voltage are specified as technical parameters for thick filmheating elements.

These elements are manufactured within 15 % tolerance of resistance (power).

TECHNICAL PARAMETERS OF HEATING ELEMENTSThe technical parameters of electrical heating elements mentioned in this chapter are to be considered

as basic data only. They are intended for customer's orientation when discussing an order with the SalesDepartment of Backer Elektro CZ.

These parameters are essential when the customer's requirements cannot be satisfied with our offer ofseveral hundreds types of heating elements from our assortment. In such a case, a consultation with theTechnical Department of Backer Elektro CZ is necessary. Thus, a heating element with requiredcharacteristics for the given application can be designed and manufactured.

SHAPES AND TYPES OF HEATING ELEMENTS

An electrical heating element consists usually of one or more tubular heating rods, connecting meansfor electrical connection, and heads or flanges for mechanical fixing.

The heating rods can be of circular or flat-oval cross section. The sheath of the heating rod consists ofa metal tube of specific dimensions that is made of a suitable material, according to the givenapplication. The surface of this metal sheath can be further treated so that to increase its resistanceagainst surrounding environment. To improve the heat transfer of elements for heating of air and othergases, these can be provided with ribbing made of a steel tape wound perpendicularly around theheating rod. Some heating elements intended for special purposes can be imbedded into a casting ofrequired shape. For this purpose, mostly aluminium is used.

A resistive heating wire with output pins or output stranded wires is inserted inside the metal tube intoan insulating material. The tube is then sealed and closed so that its inside active parts are thoroughlyprotected from all influences from the environment.

The heating rods, as the basic semi-product, can be processed in variety of shapes, meeting therequirements of the customer, depending on the final equipment where they are applied (up to amaximum operating pressure of 6.4 MPa).

An electrical heating element can be optionally equipped with various types of heads or flanges formechanical fixing at assembly. The heating element can also be equipped with suitable connectingmeans for connection to the electrical circuit.

All electrical heating elements manufactured by Backer Elektro CZ are designed and produced inaccordance with standard EN 60335-1.

At Backer Elektro CZ, we are proud to have mastered the technology of thick film heating elements.This advanced technology process provides a perspective opportunity to use heating elements of thiskind in ordinary areas of applications, as well as in brand new ones.
